Leading the Way as a
Reaction Injection Molding Company

Why You Should Choose a Custom Reaction Injection Molding Manufacturer for Your Parts

• Large, lightweight parts – RIM produces components with a high strength-to-weight ratio, making it ideal for large, lightweight parts.
• Superior acoustic and thermal properties – The material’s inherent properties provide excellent sound absorption and thermal insulation.
• Tunable density and thickness – RIM materials can be adjusted to meet specific application needs from soft-touch to rigid, high-impact characteristics.
• Thermal stability – Reaction injection molding parts maintain their properties across a wide range of temperatures, ensuring durability in demanding environments.
• B-side features and insert encapsulation – RIM allows for the incorporation of complex geometries and embedded inserts, enhancing functionality and design.
• Cost-effective tooling – With a lower tooling investment than traditional injection molding, RIM is cost-effective for both low- and medium-volume production runs.
• Rapid prototyping – Quickly develop and test prototypes, accelerating the product development cycle.
• Complete design freedom – RIM’s flexibility enables innovative designs and complex shapes that are difficult to achieve with other manufacturing processes.

When RIM Is the Right Solution for Your Project

• Working with a custom reaction injection molding manufacturer is an excellent solution for producing large, lightweight parts that require a high strength-to-weight ratio and extensive customization options.
• RIM’s unique process allows for the creation of components with complex geometries, including varying wall thicknesses and intricate attachment features, making it ideal for parts that demand both design flexibility and structural integrity.
• This method is particularly well-suited for low- to mid-volume production runs, typically ranging from 500 to 10,000 units annually, depending on part size.
• The process of reaction injection molding has comparatively low tooling costs, making it a cost-effective choice for projects that require complex designs but do not justify the expense of traditional high-volume molding methods.

Creating RIM Parts: From Concept to Completion

1. The tool (typically aluminum but can be epoxy) is opened to prepare the surfaces.
2. Tool surfaces are prepared with a mold release to ensure material does not bond to the cavity or core.
3. The cavity of the mold is painted, or a cover material is inserted into the mold.
4. If inserts or other components are required, they are loaded into the mold.
5. Once the cavity of the mold is prepared, the material can be injected into the mold. There are two methods of introducing the material to the mold:
   1. Open pour method – The mold is open, and the material is poured or injected into the cavity. The mold must then be quickly closed.
   2. Closed pour method – The mold is closed, and the material is injected into the mold utilizing a mix head.
6. Once the material is in the mold, there is a curing period for the material to harden and stabilize.
7. Once the material is cured, the mold can be opened, and the part can be removed.
8. Depending upon the material and product application, the part can then go to a trim process and other value-added steps.

Problems We Solve as a Custom Reaction Injection Molding Manufacturer

• Attachment and Assembly Challenges – Attaching parts to an assembly can be challenging, especially when rust and corrosion are concerns. Fortunately, this problem can be solved by choosing nonferrous attachment methods, such as wood, plastic, or aluminum, which can be used to prevent rust and corrosion, ensuring a durable and reliable connection.
• Surface finish requirements – With RIM parts, you can achieve a variety of a-surface finishes, including overmolded and soft-touch surfaces.
• Cost-effective tooling – High tooling costs can be a challenge, but RIM’s low-pressure process reduces tool construction requirements, allowing the use of cast aluminum, epoxy, or even wood for prototyping.

Frequently Asked Questions

What are your certifications?

AdvancTEK is IATF 16949 and ISO 14001 certified. As part of our APQP process, we also collaborate with customers early and often to define CSRs (customer-specific requirements) to ensure we are meeting all customer requirements.

Can you offer design and engineering support?

Yes! We have a team of design, product, process, and manufacturing engineers that work with customers at various stages of their development cycle. We offer full design and development services, in addition to DFM (design for manufacturability) and product design recommendations. As part of any proposal development, we will identify initial part design issues that may affect manufacturability, cost, quality, or other key items.
